It features a hipped slate roof with a short ridge. The front has 12-paned sash windows, with the ground floor windows having segmental heads, all equipped with slate cills. The central entrance consists of a 6-panel door, which is divided into two sections, located beneath a flat-roofed timber porch that has latticed work on the sides. There are prominent rectangular chimney stacks on the roof slope to both the left and right.
